Product Description

DIODE Specifications

This diode, or high voltage diode, is used in microwaves. It is an electrical current control device that ensures power flows in one direction and not the other way. If your microwave produces no heat, heats inconsistently, or gets noisy, replacing this part can be the solution. The tools needed for this replacement are a nutdriver, pliers, and screwdrivers. First remove the microwave cover, then remove the old part by disconnecting the small thermostat. Replace with the new diode. Remember to use the diagram provided by the manufacturer for more instructions.

Maytag MMV 5219 DH1 microwave does not heat and makes loud grinding noise. turntable motor checks okay. I'm wondering If it could be the magnatron.
For model number W11256462
Hello Rich, thank you for your question. These symptoms can be caused by a defective diode, capacitor, or magnetron. Your microwave oven is capable of giving you a serious electrical shock, even when it is unplugged. We strongly suggest you seek the assistance of an appliance repair technician when conducting any microwave oven repair. We hope this helps.

MW won't heat. all else works. replaced diode and fuse and still won't heat. tested old and new parts with voltmeter and they all tested as functioning. Is there a 2nd fuse or could it be the magnetron?
For model number UMV1160CB-3
Hello William, thank you for contacting us. We would recommend checking the magnetron thermostat, part number PS8691721, thermistor, part number PS2180211, and the high-limit thermostat, part number PS2361102. Please do a continuity test on these parts using a multimeter. If this does not help the issue is probably related to the magnetron, part number PS11757171. Customer service is always available to help you place an order if you are having trouble doing so. Good luck with your repair.

Would replacing the diode on the mother board help troubleshoot the lights underneath from staying on?
For model number MMV4205DS4
Hello Laurie, thank you for the question. According to our research, the diode, part number PS12584264, is an electrical current control device that ensures power flows in one direction and not the other way. A faulty diode could be an issue but we would recommend also checking the door latch, part number PS11722531, and door switch, part number PS2361113. Please reach out to customer service if you need help placing an order. Glad to be of help!

no heat
this problem started two months ago when my micro quit heating up, after all the research most agreed it was the magnetron. taking the micowave apart is not to difficult just make sure you bag all the screws accordingly. the high voltage area is on the right hand side behind a panel. caution there is a capacitor that will bite if your not careful, need to short the circuit between the two connectors with an insulated screw driver it will make a small pop or let it sit for awhile and it will discharge by itself. The magnetron worked for two days then quit, after more research i took it apart again and tightened up all the connections. Worked great on the bench but when i got it back up on the cabinet two dayslater kaput again. so again i take it down and replaced the two cheapest parts in the high voltage system, magnetron thermst fix, and h.v diode. benched tested it this time for 3 days cooking anything that i could think of, worked great. its been one week now afer installtion and it is still working.

Microwave not heating, working otherwise
This was an over-the-range microwave/hood, so the replacement parts were significantly cheaper than buying a new unit.

Take microwave down (really a two-person job). Remove microwave cover (about 20 philips screws), discharge HV capacitor by shorting terminals to microwave case. Take photos before pulling anything apart. Remove plastic ducting covering part of the magnetron (3 philips screws). Remove old magnetron (4 Torx screws), need to disconnect small thermostat on side (2 philips screws) and replace with new magnetron. Replace HV diode (screw on one end, other end simply plugged into capacitor terminal). Put everything back together and it works fine.

Microwave made very loud noise while on. No heat.
Unless you have a very comfortable background with electronics and electricity, I don't necessarily recommend taking apart a microwave. If you are very handy and are going to be VERY cautious to follow the rules of discharging caps and testing voltages before moving forward, then go for it. That said, I took the microwave off and apart. Not knowing where to find the parts, I was fortunate that the installer put the instruction book for the microwave inside the front vent slot above the touchpad for reference. it details the location of every part and it tells you very clearly what each part you test should show specific to this microwave on your multimeter. Find this guide online if you don't have it. Turn on the microwave for 20 seconds with a glass of water to make sure it's not heating - that with the noise means it's eeither the magnetron, cap, or diode. Read the notes on this site for all of the basic things to look for with the magnetron, diode, and capacitor. Once comfortable with the guide, locations of those devices, and how to test, then take it down and apart. Unfortunately, I didn't do all those things in that order, and it only wasted a lot of time trying to find the parts. Once I found the parts and put all the screws and covers back for all the areas that didn't need to be accessed for the repair, testing went quickly. The diode was bad. Ordered a new one and had it in 3 days or so. That means your microwave will be apart and sitting somewhere for a little while until you get the part and have time to repair it. Putting the diode back isn't too bad. Reassemble the microwave and put it back up again. If i had to do it again, it would take me 20 to 30 minutes once the microwave was down and on a table. Also, I used some bricks with towels over them or you could use some sawhorses to keep the microwave elevated so you can plug it in and run it after installing the new component. Again, make sure you discharge the cap before touching anything again even if you didn't run it, but just plugged it in.

Humming sound, not heating.
I turn off the income electricity by shutting down the corresponding circuit breaker. Then, I removed the control panel from the microwave which gave me access to the capacitor and adjacent diode. After that i unscrewed the defective diode and replaced it with the new one and BINGO!

Wolud not heat or cook anything.
Instead of telling you, i have question do you have any instructions on how to do the repair. It would have helped save time on the repair.

This job took longer then it should have, becasue I did not start right in the begining. I did figure it out quickly after the wrong start.

You were a big help in picking the right part to correct the problem. You should be able to help with the repair. Thank You

Microwave would run but not heat up the food
Removed the microwave from above the oven by loosening the two screws above the microwave. As the unit tilted outward lifted up and the whole unit came out all the time feeding the power cord through the cutout for the power cord. After it was out removed the cover and identified the capacitor and made sure it was discharged and removed and replaced the diode. tested before reinstalling and it heated up just fine. Reversed order and reinstalled . Very easy job maybe a second hand to help fish the power cord when installing and removing.
